Why it made the list

One of the very few U.S. vendors that periodically accepts credit card and Apple Pay alongside Zelle. Same-day shipping on orders placed before 2PM EST. Every batch comes with a USA lab-verified COA. Clean catalog: BPC-157, Tirzepatide, Retatrutide (listed as GLP-3 RT on their site), NAD+, GHK-Cu. Discreet packaging, responsive support.

We have a partnership with Xeno Peptides and earn a commission when you use our link or code. We only partner with vendors we genuinely recommend.

How to verify a COA

1

Request a batch-specific COA, not a generic one. The batch number on the COA must match the batch number on your vial.

2

Check the lab name. Legitimate labs include Janoshik, Colmaric, Analytical Noise, and other ISO-accredited facilities.

3

Verify the batch number directly on the lab's portal if available. Janoshik and Colmaric both offer public batch lookup.

4

Red flag: if a vendor cannot provide a batch-specific COA or the batch number is not verifiable, do not order.
